With fifteen years of experience, our experienced team employs the latest in instrumentation and specialized synthetic techniques to deliver high quality products on time at a great price.

Abgent has over fifteen years of experience producing recombinant proteins in E. coli and mammalian cells (CHO and HEK293, etc), and we have added a powerful yeast expression platform to our menu of services. With state-of–the art molecular biology and protein biochemistry labs, we work with our clients to rapidly evaluate in parallel to identify the optimal expression system for candidate proteins.

Certify that your antibodies work, while saving time and money. Abgent’s experienced staff custom validates more than 1,000 antibodies each month in Western Blot (WB), Immunofluorescence (IF), Immunohistochemistry (IHC), Flow Cytometry (FC) and additional applications. Proper validation with controls and optimization ensure the quality of the antibody, and establish confidence in your results.

Thousands of laboratories across the world have published research that depended on the performance of biological reagents manufactured by Abgent to advance their research. Check out links to articles that cite our custom service antibodies, peptides, and proteins in major peer-reviewed journals, organized by research category.

18,000+ products cover the ten top research categories, including cancer, metabolism, cardiovascular, neuroscience, and stem cells. Each antibody is crafted with care according to rigorous protocols for immunogen design and preparation, presentation to host animal, and high-affinity purification against the antigen. Quality is embedded in the production process to assure the best antibody for you.

Abgent develops 1000+ new products per year. We provide tools for path-breaking research by developing antibodies that detect a comprehensive library of novel and established targets. For established targets we seek to add antibodies that recognize new epitopes, including post-translational modifications such as phosphorylation and methylation. For new targets we consult with leading experts to accelerate development of antibodies that will propel state-of-the-art research in cellular health and disease.

Abgent offers custom and catalog peptides to pharmaceutical, biotechnology companies and academic institutions worldwide. All peptides are manufactured in the United States to exacting standards in support of U.S. and international clientele. Custom peptide services include long peptides (>100mer), cyclic peptides, difficult sequences, fluorescent labels, and phosphopeptides.

The majority of Abgent antibodies are produced using peptide immunogens. These immunospecific peptides can be used as blocking agents when using the complementary antibodies in a range of applications.

Researchers worldwide depend on Abgent FLcDNA clones to accelerate their research. Expression-ready clones are convenient solution that decreases the time required to start an experiment and increases the chances of success.

The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.

The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

Western blotting (0.5-4 µg/ml). However, the optimal concentrations should be determined individually. Jurkat cell lysate can be used as a positive control. The antibody recognizes 16 kDa human KiSS-1 in Western blot analysis with Jurkat cell lysate. Blocking peptide is available separately.

KiSS-1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.

Protein Information

Name

Kiss1

Function

Metastasis suppressor protein. May regulate events downstream of cell-matrix adhesion, perhaps involving cytoskeletal reorganization. Generates a C-terminally amidated peptide, metastin which functions as the endogenous ligand of the G-protein coupled receptor GPR54. Activation of the receptor inhibits cell proliferation and cell migration, key characteristics of tumor metastasis. The receptor is also essential for normal gonadotropin-released hormone physiology and for puberty. The hypothalamic KiSS1/GPR54 system is a pivotal factor in central regulation of the gonadotropic axis at puberty and in adulthood. Intracerebroventricular administration induces an increase in serum LH and FSH levels in prepubertal male and female as well as in adult animals.

Cellular Location

Secreted.

Tissue Location

Weak in all tissue types with highest levels in lung and 15- 17-day embryos. Expressed in areas of the hypothalamus implicated in the neuroendocrine regulation of gonadotropin secretion, including the anteroventral periventricular nucleus, the periventricular nucleus, and the arcuate nucleus.

Background

KiSS-1 has been reported to suppress metastases of melanomas and breast carcinomas without affecting tumorigenicity. Human KiSS-1 transcripts are predominately expressed in the brain and placenta. Expression of KiSS-1 reduces the level of NFkB p50/p65 binding to the MMP9 promoter and correlates with diminished expression of the 92 kDa type IV collagenase (MMP-9). KiSS-1 may regulate events downstream of cell-matrix adhesion in mechanisms involving cytoskeletal reorganization.
